Let’s substitute \( x = -2 \) and \( y = 3 \) into the expression \( (6x - y) - 2(3x - 5y) \). First, calculate \( 6x - y \): \[ 6(-2) - 3 = -12 - 3 = -15 \] Next, calculate \( 3x - 5y \): \[ 3(-2) - 5(3) = -6 - 15 = -21 \] Now calculate \( -2(3x - 5y) \): \[ -2(-21) = 42 \] Finally, put it all together: \[ -15 + 42 = 27 \] Thus, the value of the expression is \( 27 \).
